If your Honeywell thermostat has been set to 68 degrees and yet you still wake up to a cold home, it may be because the message “heat on” keeps appearing but doesn’t actually turn on your furnace.
Sometimes this occurs if the temperature sensor is malfunctioning. It could be blocked or damaged, or its batteries may have run out of charge.
If your Honeywell thermostat isn’t turning on, there are a few things to check to figure out why. These include batteries, settings and furnace.
Battery life can diminish over time, leading to malfunctioning of Honeywell thermostats. This may occur if the battery reaches its end of its usefulness or if not enough power is being supplied to operate the thermostat properly.
A quick way to check the batteries on your thermostat is by switching it off and looking at its circuit breaker box for a few minutes. If you see a tripped breaker, this indicates that your thermostat isn’t receiving enough power to function correctly.
Another reason your thermostat may not be turning on heat is if the mercury switch in the thermostat isn’t level. To fix this, loosen its mounting screws and adjust until your thermostat is perfectly straight.
It’s wise to have a professional inspect the thermostat’s wiring for any potential issues. This could involve rewiring or changing connections on the thermostat.
Thermostats are essential to your home’s comfort and energy efficiency. Without them, you won’t have any control over the temperature in your room.
Honeywell WiFi thermostats give you remote access to your home’s HVAC system and save money on utility bills. Plus, this smart thermostat learns your temperature preferences and adjusts settings accordingly.
Furthermore, Honeywell WiFi thermostats can monitor your HVAC health and send maintenance reminders and savings suggestions directly to you. If you have any queries about the advantages of a Honeywell WiFi thermostat, get in touch with one of Rheem Pro Partners in Colorado or Wyoming today!
If your Honeywell thermostat isn’t flashing heat and the temperature isn’t staying consistent, the issue could be with your furnace. Faulty parts, clogged filters or blades, and setting high temperatures all could contribute to furnace malfunctioning.
If your gas furnace is malfunctioning, replacing the pilot ignitor may help fix the issue and keep your home comfortable. Alternatively, calling a professional to replace it might be beneficial as well. Ultimately though, if these steps don’t yield results then it may be necessary to completely replace your furnace.
Check the Batteries
If your honeywell thermostat is reading “heat on” but there’s no heat, the first step to take is check the batteries. These are an integral part of the thermostat system and help regulate indoor temperature accordingly.
When your thermostat displays a low battery indicator, this means the batteries need replacing. This is usually an established feature on Honeywell thermostats and usually comes with a warning to make sure you replace them before they completely drain out.
Once you’re ready to replace the batteries in your Honeywell thermostat, find a reliable supplier and order some new ones ahead of time. This will guarantee you have fresh batteries when needed and help save you money in the long run.
Thermostats typically run off two AA alkaline batteries and there may be an indicator that lets you know when it’s time for replacement. However, this depends on your model and how it has been set up.
When you are ready to remove the batteries from your thermostat or battery compartment tray, locate the cover on either device and carefully unscrew it. Doing this should allow for safe removal of the batteries without damaging anything in the process.
Once you’ve taken out the old batteries, take your time inserting the new ones, making sure they are properly placed. Be sure to note both positive and negative ends of each battery so you can dispose of them correctly.
Once the batteries have been replaced, your thermostat should work normally again. If not, try realigning both the faceplate and baseplate to make sure they are both in their correct positions.
To reunite them, pull them apart and push the baseplate down on the faceplate. You should be able to get them back together without too much trouble.
If your honeywell thermostat still won’t turn on after replacing the batteries, it could be due to an issue with their polarity. We suggest trying a different brand of battery to see if that solves your issue.
Check the Thermostat Settings
If your thermostat displays the correct temperature but your house isn’t getting heated up, there could be several causes of why. A dirty filter, malfunctioning pilot ignitor, or low battery power could all be to blame.
A Honeywell thermostat is an integral component of a home’s HVAC system, helping maintain comfortable temperatures while controlling energy costs. You can program it to turn on automatically when you enter the house or off when you depart.
Honeywell has been manufacturing thermostats for 50 years, ranging from programmable and non-programmable models to mechanical ones.
Most thermostats consist of a dial and lever combination to set a temperature. Some even feature fans for added convenience.
They come in a range of shapes, such as round and rectangular. Round thermostats usually function only for heat or cooling and feature a dial; on the other hand, rectangular models tend to only provide cooling functionality.
Levers with levers let you switch between heating and cooling, turn the fan on or off, and increase or decrease airflow. Plus, some are programmable with additional buttons for specific functions.
Some are digital, featuring a screen that displays the time. This enables you to set temperature and other settings on your device without needing to go directly to your HVAC unit.
Some Honeywell thermostats can be secured, requiring that only those with the correct password can make changes. To find out which model this applies to, consult your owner’s manual for more details.
The initial step should be to reset your thermostat’s settings. This can be done either through the touchscreen or using a phone app.
If you’re not sure how to unlock your thermostat, the process is generally the same for all models: press the Unlock button on the screen and insert a four-digit PIN into the prompt.
If your Honeywell thermostat displays heat on but there’s no heat, it could be due to a failed battery. In this instance, take out the old batteries and replace them with fresh ones before resetting the thermostat back to factory settings.
Check the Furnace
If your honeywell thermostat displays heat on but there’s no warmth, make sure the furnace is turned on and set to “heat.” Next, increase the temperature setting slightly and wait a few minutes for the system to kick in.
If the above doesn’t solve the problem, contact a professional to inspect your furnace. They can check your thermostat, battery and flame sensor on the device.
Another common issue is a broken gas valve, which can cut off fuel flow to your furnace. This issue could occur by accident or someone working on it who forgets to open the valve.
No matter the cause, you should have your gas valve checked by a certified technician to make sure it’s in the open position. A closed valve could lead to a leak and dangerous levels of carbon monoxide in your home.
Additionally, you should inspect the flame sensor on your furnace to make sure the burners have ignited once the gas valve opens. These sensors can become coated with soot and carbon deposits over time, so regular cleaning is necessary in order to keep them functioning optimally.
Finally, inspect the vent motor on your furnace for proper combustion. This motor may be malfunctioning and replacing it may be necessary.
Your furnace’s heat exchanger is a tube-shaped metal structure that blends water and air to heat the furnace during operation. As it ages, it may become rusty or warped, leading to decreased efficiency in operation.
When this occurs, you may hear a humming sound coming from the vent motor or an ignitor that won’t light. If the noise is coming from your fan, this could indicate an issue with its pressure switch which prevents it from starting when there is insufficient pressure to run it.
Every autumn, it’s wise to have your furnace professionally inspected for safety. Doing this can save the expense of having a repairman come out and prevent an expensive accident from occurring.
